You can apply the same thought process to gays, lesbians and bisexuals. Many times there is a thought about coming out to someone, but there may be a string of unintended consequences. Excluding people who are transgender (mind/body mismatch), crossdressers fall into the same category. However, we don't ask people "Why do you like being gay?" or "Why are you gay?". We tend to take it at face value. Basically I think you have to take the same approach with crossdressing and crossdressers.
